This portage is only 800 metres long, but it goes steeply down from Twin Lake to Amor Lake - you lose 52 metres in about 500 metres of the trail making this a 10% grade. This grade is a very good reason why you want to do the circuit counter clockwise.
The trail starts across the road from the Twin Lake forest rec site and goes along the left side of the creek so you need to turn left over the road bridge to get to the trailhead.
The trail is in good condition but when I walked on the May long weekend, I found a number of fallen trees across the trail By the time we went through at the start of August, someone had cut away the fallen trees.
The launch point only has space to have one canoe in the water at a time.
